Product Overview and Core Advantages
The 511/670 F thrust ball bearing is a metric system component engineered for pure thrust applications. This open-type bearing excels in handling high axial dynamic and static loads, with ratings of 191,700 lbf and 1,507,500 lbf respectively. Manufactured from 52100 Chrome Steel for both rings and balls, it ensures exceptional durability and wear resistance. Its robust construction and precise dimensional tolerances make it ideal for heavy-duty machinery requiring reliable axial support under demanding conditions.
511/670 F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 511 | Designates a thrust ball bearing series with a flat seating surface on both washers. |
| 670 | Indicates the bore diameter of 670 mm. |
| F | Signifies a carbon steel cage (in this context, the provided specification indicates a Stainless Steel cage, which is a high-performance alternative). |
Structural Features and Performance Benefits
- High Load Capacity: The single-direction thrust design is optimized to withstand exceptionally high axial static and dynamic loads, making it suitable for applications with significant force in one direction.
- Precision Engineering: Tight dimensional tolerances on the bore diameter and outside diameter ensure a precise fit, contributing to stable operation and extended service life.
- Durable Cage Construction: The stainless steel cage provides excellent strength and corrosion resistance, maintaining ball alignment and integrity at the limiting speed of 0.6 x 1000 rpm.
- Wide Operating Range: A temperature range of -30°C to 110°C allows for reliable performance in various industrial environments.
- Compliance and Safety: The bearing is ROHS and REACH compliant, ensuring it meets modern environmental and safety standards.
